Polyphony mu Digital Piano

Zambiri (kuchokera ku Chilatini "polyphonia" - mawu ambiri) ndi mawu omwe amatanthauza kumveka kwa mawu ambiri panthawi imodzi, kuphatikizapo zida. Zambiri idayamba mu nthawi ya ma motets ndi ma organums akale, koma idakula zaka mazana angapo pambuyo pake - mu nthawi ya JS Bach, pomwe. polyphony anatenga mawonekedwe a fugue ndi mawu ofanana kutsogolera.

Polyphony mu Digital Piano

Mu piano zamakono zamakono ndi makiyi 88, 256 mawu polyphony ndizotheka. Izi ndichifukwa choti purosesa yamawu mu zida zamagetsi imatha kuphatikizira zolumikizana ndi kugwedezeka kwa mafunde munjira zosiyanasiyana. Umu ndi momwe mitundu ingapo ya polyphony imabadwira m'makibodi a chitsanzo chamakono, pa chizindikiro chomwe kuya ndi kulemera, kumveka kwa phokoso la chida chimadalira mwachindunji.

Kuchulukira kwa mawu mu piyano ya polyphony parameter, ndipamenenso woimbayo amatha kumveka mosiyanasiyana komanso mowala.

Mitundu ya makhalidwe

The polyphony piyano yamagetsi ndi 32, 48, 64, 128, 192 ndi 256 - mawu. Komabe, opanga zida zosiyanasiyana amasiyana pang'ono kusankha makina, kotero ndizotheka kuti piyano yokhala ndi 128-voice polyphony, mwachitsanzo, ikhale ndi phokoso lolemera kuposa chipangizo chokhala ndi 192-voice polyphony.

Chodziwika kwambiri ndi mtengo wapakati wa digito ya polyphony ya mayunitsi 128, omwe amafanana ndi zida zamaluso. Inde, mutha kuyang'ana pazigawo zazikulu (mawu 256), komabe, monga momwe zimasonyezera, ndizowona kupeza chida chodabwitsa chomwe chili ndi mphamvu zambiri zama polyphonic. Polyphony wolemera sikofunikira kwa woyimba piyano wa novice, popeza wosewera woyamba sangayamikire mphamvu zake.

Chidule cha piano za digito

Zina mwazosankha za bajeti, mutha kuganiziranso ma piano apakompyuta okhala ndi mawu amtundu wa 48. Zitsanzo zoterezi, mwachitsanzo, ndizo Chithunzi cha CASIO CDP-230R ndi CASIO CDP-130SR . Ubwino wa piyano za digito ndi mtengo wa bajeti, kulemera kopepuka (pafupifupi 11-12 kg), kiyibodi ya 88-kiyi yolemetsa komanso zida zoyambira zamagetsi.

Ma piano okhala ndi mawu 64, mwachitsanzo, ndi Yamaha P-45 ndi Yamaha NP-32WH zitsanzo . Chida choyamba chimakhala ndi kapangidwe ka thupi kapamwamba kwambiri kachitsanzo chotsika mtengo, chaching'ono (11.5 kg) komanso ntchito yocheperako. The piyano yachiwiri ndi yam'manja ( synthesizer mtundu), wokhala ndi choyimbira nyimbo, metronome, opareshoni ya maola 7 kuchokera ku batire yolemera 5.7 kg.

Oimba apamwamba kwambiri amafunikira chida chokhala ndi mawu osachepera 128. Piyano yokhala ndi mphambu 192 idzakhalanso mwayi wopeza woyimba piyano wovuta kwambiri. Mtengo ndi khalidwe zimaphatikizidwa bwino mu Chithunzi cha Casio PX-S1000BK . Chida ichi cha ku Japan chili ndi zinthu zambiri, kuyambira pakuchita nyundo anzeru Scaled Hammer Action Keyboard mpaka kulemera kwa 11.2 kg. Piyano yamagetsi ya PX-S1000BK ili ndi izi:

• kiyibodi yolemera makiyi 88 ​​yokhala ndi magawo atatu okhudza kukhudza;
• kuyankha kwa nyundo, damper resonance, touche - controller;
• ntchito ya batri, USB, nyimbo zachiwonetsero zomangidwa.

Ma piano apakompyuta okhala ndi polyphony parameter ya mayunitsi 256 adzakhala zitsanzo za chizindikiro chachikulu cha polyphony pakumveka. Zida zamtunduwu nthawi zambiri zimakhala ndi mtengo wapamwamba, komabe, ponseponse potengera mapangidwe komanso mawonekedwe awo aukadaulo, ndi zitsanzo zapamwamba kwambiri. Piano ya digito ya YAMAHA CLP-645DW yokhala ndi makina apamwamba a katatu komanso kiyibodi yabwino kwambiri yamatabwa ngakhale zowoneka ngati chida chamtengo wapatali choyimbira. Zina mwa makhalidwe a chitsanzo ndizoyenera kudziwa:

• kiyibodi ya makiyi 88 ​​(kumaliza kwa minyanga ya njovu);
• zosintha zopitilira 10 zokhuza kukhudza;
• ntchito ya kukanikiza kosakwanira kwa pedal;
• Chiwonetsero chathunthu cha Dot LCD;
• Damper ndi chingwe kumveka ;
• Tekinoloje ya Intelligent Acoustic Control (IAC).

Komanso chitsanzo chabwino kwambiri cha chida cha digito chokhala ndi 256-voice polyphony chidzakhala piyano ya CASIO PX-A800 BN. Chitsanzocho chimapangidwa mumthunzi wa "oak" ndikutsanzira kwathunthu mawonekedwe a nkhuni. Lili ndi ntchito ya emulating konsati acoustics, ndi AirR mtundu phokoso purosesa ndi 3-level kukhudza kiyibodi.

Mayankho pa mafunso

Ndi chizindikiro chanji cha polyphony ya piyano ya digito chomwe chingakhale choyenera kwambiri pamlingo woyamba wamaphunziro amwana kusukulu yanyimbo?

Chida chokhala ndi polyphony ya mayunitsi 32, 48 kapena 64 ndichoyenera kuphunzitsidwa.

Ndi mtundu wanji wa piano wamagetsi womwe ungakhale ngati chitsanzo cha mtengo ndi mtundu wa 256-voice polyphony? 

Chimodzi mwazinthu zabwino kwambiri zitha kuonedwa ngati piyano Medeli DP460K

Kuphatikizidwa

Zambiri mu piyano yamagetsi ndi chinthu chofunika kwambiri chomwe chimakhudza kuwala kwa phokoso la chida ndi mphamvu zake zomveka. Komabe, ngakhale ndi masinthidwe apakatikati a polyphony, mutha kutenga piyano yayikulu ya digito. Mitundu yokhala ndi ma polyphony apamwamba kwambiri idzakhala njira yabwino kwambiri yopezera akatswiri komanso odziwa zambiri.
